QUASAR™ MRI⁴ᴰ Motion Phantom

Compatible Machine(s): LINAC, Ring-Gantry System, SRS Systems, MR-LINAC, MR-SIM, SGRT

Application(s): Motion Management, MR Guided Radiation Therapy, Machine Targeting

 

Quasar MRI⁴ᴰ is the world’s first MR-safe programmable motion phantom. Adapting for motion in Radiation Therapy requires advanced QA tools and the MRI⁴ᴰ enables you to develop, test and validate advanced 4D treatment delivery protocols on MR-sim and MR-Linacs. 

Interchangeable inserts are available for imaging, planning, targeting, dosimetry and delivery QA. The included software provides tools to create, import, edit and stream patient-specific respiratory waveforms.
